Serial reading problem

hi all, i would like to ask,

i'm currently sending a value for example 1000 from my c# to the arduino.

i am reading from serial 3 btw. this is how i read from the arduino:

int value;

if (serial3.available >2){
value = serial3.read();
serial.print(value);
}

but when i open my serial monitor, the value is not 1000, it is within 0 to 255. what can i do if i want to receive my exact value of 1000?
tiv!

Serial reads byte values - 0/255 only, you need to read an integer it seems.

This post may help.

value = serial3.read();

You're only reading a single byte, so it will be between 0 and 255.

Try something like

value = (serial3.read() << 8) + serial3.read();

Assuming the data is binary and transmitted MSB first.
